We're running PHP 5.2.5 on an IIS 7 Server and we're having problems making PHP errors visible... At the moment whenever we have a PHP error the server sends back a 500 error with the message "The page cannot be displayed because an internal server error has occurred."

This might be a good setting for production websites but it's rather annoying on a development server... ;-)

I have tried configuring php.ini to display errors to the screen as well as log them to a specific folder but it seems that the Server catches all errors before and prevents and handling by PHP...

Does someone know what we have to do to make IIS display PHP errors on screen? Any links, tipps or tutorials on the subject would be appreciated!

Just to double check, do you have logging set to E_ALL, and display_errors enabled in your php.ini? Usually this is enough to display these errors in IIS 7.

Next, take a look at your IIS settings, as it may be set to only show error messages locally. In the IIS 7 configuration editor this is under system.webServer->httpErrors. You will need to change errorMode to Detailed from DetailedLocalOnly. Obviously this now means anyone browsing your site will be able to see the error.

Alternatively, if you want to keep them local you can RDP to the server and run the app from there, if you can.

You can do this easily using the IIS Manager GUI. Select your Site and double-click Error Pages. Then hit 'Edit Feature Settings...' and select the 'detailed errors' option instead of the default 'detail errors for local requests and custom error pages for remote requests'. Voilà, simple as that!
